Sand mastic in Slamannan
We work across Slamannan renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. If you’re dealing with window mastic to renew ahead of painting and failed mastic on an exposed elevation, we can put it right, on brick reveals, tenement windows and period & listed homes alike.
Outdoor sealant needs a dry surface, so window work around Slamannan is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Sand mastic in Slamannan: local notes
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
In and around Slamannan, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

The process
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours per window, depending on the condition of the joints in most cases. For a place like Slamannan, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints

Slamannan questions
Do you work for landlords with property near Caldercruix station?
Yes, landlords and agents are among the people we work for. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Will you come out to Slamannan?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and shaped to suit the surround.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you guarantee sand mastic work?
Every job comes with our 12-month guarantee.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What the job involves on each surface
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It suits older brickwork.
Period and listed homes
Period homes look their best with traditional materials.
Do you need sand mastic in Slamannan?
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
Keep an eye out for these signs:
- Modern sealant on a period surround
- Crumbling sand mastic round a window
- Cement or filler used on old window joints that has cracked
- Gaps where the frame meets the masonry
For landlords with property near Caldercruix station, older sash windows in a rental need their mastic kept sound to keep the weather out.

What happens if it’s left?
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
